Abstract: An information processing apparatus includes a storage unit and a processing unit. The storage unit stores a command for acquiring configuration information from a target apparatus, in association with the name of the apparatus. The processing unit acquires the name of the target apparatus that is subjected to acquisition of configuration information, by accessing the target apparatus present on a network, based on access information for accessing the target apparatus. The processing unit acquires the configuration information from the target apparatus, by causing the target apparatus to execute the command associated with the name of the target apparatus. Further, the processing unit creates a configuration information list listing the configuration information.

Abstract: A data processing system having an efficient logging mechanism which stores log records for repairing a file system when its consistency is lost. When there is a transaction attempting to update metadata stored in metadata volumes, a metadata loading unit reads the requested metadata objects out of the volumes and loads them to a metadata cache. At that time, a metadata manager updates its internal database to record from which metadata volume each metadata object has been fetched. Each time the transaction updates a metadata object in the cache, a log collection unit collects a copy of the updated metadata object, together with a volume ID which indicates its home metadata volume. The collected data is temporarily stored in a log buffer, and finally saved into a log volume by a log writing unit.
